Under the influence of its drive force, a snowmobile is movingat a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 125 kg. Underthe influence of a drive force of 210 N, it is movingat a constant velocity whose magnitude is 6.41 m/s.The drive force is then shut off. Find (a) thedistance in which the snowmobile coasts to a halt and(b) the time required to do so.
An oscillator consists of a block attached to a spring (k = 475 N/m). At some time t, the position (measured from the system's equilibrium location), velocity, and acceleration of the block are x = 0.420 m, v = -11.9 m/s, and a = -139 m/s2. a)Calcula..
